'1"lla'im. (C1. .2o- 55) This invention relates to certain novel improvements in stormV windows.

More particularly the invention has reference to a storm window for attachment to a window sash for movement therewith whereby to allow for ventilation in a room by merely raising or lifting the window sash to which the storm sash is attached.

An object of the invention is to provide astorm sash of an area less than the area of the window sash but greater than the area of the transparent sheet or glass of the window sash, with the frame provided with the transparent sheet adapted to be disposed, when the frame is attached to the sash, in superimposed spaced relation with respect to the transparent sheet of the window sash.

Another object of the invention is the provision of means for permitting ready connection or attachment of the storm sash to a window sash for movement with the latter.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention ywill be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a perspective View of a Window sash showing my improved storm sash associated therewith;

Fig. 2 is a vertical sectional detail view of a window construction showing my improved storm sash associated with the window sash thereof;

Fig. 3 is a sectional detail view taken substantially on line 3 3 of Fig. 1;

Fig. 4 is a fragmentary edge perspective view of the window sash and storm sash as illustrated in Fig. 1.

The several objects of my invention are accomplished by the preferred form of construction shown in the accompanying drawings. In this connection I have illustrated a window con`- struction I5 comprising a head jamb II, a sill construction I2, and the usual side jambs I3. This window construction further includes upper and lower sash I4 and I5 suspended in any approved manner within the Window construction. To each of these sash I4 and I5, I attach a storm sash.

The storm sash is indicated generally at I 6. In Fig. 2, this storm sash I6 is attached to the inside of the sash I4, whereas the storm sash I6 of the other window sash is attached to the outer face of the sash I5. This permits either window sash I4 or I5 to be raised or lowered without being blocked or interrupted in such movement by the storm sash I5. The storm sash I6 preferably includes a frame I'I comprising frame members I8 formed of relatively light metal and substantially angular in cross section, each frame member being provided with a suitable ller block I9.

The frame Il is attached to a mounting strip 20. This mounting strip 20 is attached to the sash by any suitable means such as screws or the like and is formed of an elongated strip of material with its end portions 2| bent substantially at right angles with respect to the medial portion of the strip 20, whereby to provide lateral lugs 22 for connection by means of pins 23 to an adjacent frame Il. The medial portion of this elongated strip 25 is preferably mounted in a rabbetted portion 24 of the frame member I8 to which it is attached.

The frame member I8 opp-osite the frame member to which the mounting strip 2D is secured, provides perforated lugs 24 which are adapted for the reception of suitable screws or thumb buttons 25 to facilitate latching the frame Il to the window sash to which it is attached.

To complete the storm sash, there is provided in the frame I'I a transparent sheet 26. This sheet 26 is preferably of the area of the transparent sheet 21 of the window sash and, when the frame I'I is attached to the sash,rthis sheet 26 is disposed in spaced superimposed relation with respect to the sheet 21.

When the seasons do not require the use of a storm sash, it is necessary only to remove the pins 23 and the thumb or screw buttons 25. This permits the storm sash I6 to be removed and placed in storage until further use requires.

When the storm sash I5 is attached to the Window sash, it will be seen that the window sash may be raised and lowered without interference by the storm sash. This facilitates convenient ventilation of the room with which the window `sash are associated. As will be seen in Fig. 2, the storm sash is so related with respect to its respective Window sash that it at no time interferes with the movement or position of the window sash.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spiritof the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come Within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

A storm window comprising a frame, and means for removably connecting said frame to a window sash, said means comprising a mounting strip of elongated formation and carried by the sash and having opposite end portions extending laterally from the sash to overlap adjacent corner portions of the storm Window frame, pin connections between said end portions of said strip and said storm window frame, and slotted lug and screw connections between said storm Window frame and said sash, substantially as described.
